T 0 all whom it may concern:

Be it known that I, Rnxi': GUTLLERY, a

citizen of the French Republic, residing at Aubervilliers, France, have invented cert-am new and useful Improvements in Clutches or like Apparatus, of which the following is a specification. This invention relates to clutch actuating means.

This device is chiefly characterized by the driving force which it is desired to multiply or increase, producing a modification in the relative speeds of two parts, one of which depending on the motor, drives the other. Conjugated inclined planes are provided in the two parts and suitable ball. bearings are arranged between these inclined planes. The change of speed, thus produced between the-two parts, brings about a change of their relative lateral and axial positions, which, by means of inclined planes and balls inserted therein, is transformed into a relative movement along the joint axis of angular driving. This longi-- could .be any desired. Fig., 3 shows the detudinal movement can be utilized for obtaining any suitable drive, and in case of a clutch, acts on the adjustable part of the latter so as to produce the driving force. Moreover, for producing the change of speeds between the two parts of the servomotor or clutch thus constituted, the force to be'multiplied (in the present case that of the clutch spring), acts on an auxiliary clutch by means of which it is possible to modify at will-the speed of driving of one of the said parts and to produce the relative change in the angle of keying of the inclined planes, which mustioperate the chief clutch. 1 a In the accompanying drawings given by way of example, Figures 1 and 2 show in longitudinal and cross-section a construction of the controldevice according to this invention,' applied to a disk clutch, but it is obviousthat the clutch to be operated,

velopment of the inclined planes belonging. to the two parts, the change in the angular displacement of which, when the respective speeds of driving are varied, controls the clutch. Fig.- 4 is a modified construction of the said control mechanism.

The clutch properly speaking is consti-. tuted by alternately placed plates e, f, the plates f being driven by a box 9 secured to the motor, and theplates e driyingthe shaft Specification of Iietters Patent.

2' by means of the disk It. 1 The last plate I) of the group j is provided with a circular groove k filled with balls'd which engage with one, face of a disk a..- The .rolli ng tracks 0, while being concentric with the agis' arr-00 of the clutch, are made of wavy Patented Nov." 9, 1915.

or sinuous shape as shown in the develop-' ment in Fig. 3, so that the bottom of the groove and the corresponding face of the disk (1, form corresponding inclined planes. Owing to this arrangement,.it will be seen that the disk a will rotate with the box' 9 and the plates ,f. In fact the distance between the back of the balls Z and-the back of the first plate f is constant The only variable length is the total thickness of the packet of the plates f and e, which thickness is greater when they are separated,

that is to say disconnected, than it is when they are pressed together, that is to say thrown into gear. But in the system according to this invention, the tightening or I pressing together of-the plates f, e is produced 'by the rotation of the disk at. Owing to this rotation, the inclined planes 0 act on each other by. means. of. the balls d which modify the degree of tightening of j the plates. In order to throw the clutch into or out of gear, it will be therefore sufiicient to give to the disk a a movement so as to change its angular position relative to the plate I), the said movement rendering operative the inclined planes to move the plate I) laterally. To that end, to the principal clutch transmitting the power of the motor to the driven shaft 2', is added a small clutch m, the action of which brings about thesaid change between the parts a and b. In .fact, assuming that the apparatus is thrown out of gear, it will-be seen that the plates e f of the main' clutch are separated. The two inclined planes 0 are arranged relatively as shown in Fig. 3, sothat the available length for the loosening of the plates should be suflicient. The clutch member m is thrown (ffllt 021 y means 0 the "sk n, the sp bein compressed. If the control of tli ie clhtch i s operated the disk n will advance under the action of the spring 1), which will bring about thexthrowing into gear of the clutch gear by outside control member m. As the disk 0 is rotating, and

be arranged in a special manner. Instead of being constituted by a single spring, it

may consist of two springs of equal power. The spring 0 acts onthe cone m resting on the spring p. When throwing out of gear,

the spring p is compressed completely, While. the spring 0 gradually expands, and its length is such that when the spring p is compressed, the spring 0 no longer exercises any, pressure on the clutch.

VVhat I claim as my invention and desire to secure by Letters Patent is 1. In combination in a clutch operating device, a laterally movable plate controlling the operation of the clutch, a disk adjacent to said plate andadapted vto be rotated thereby, a clutch for changing the speed of said disk in relation to said plate, and means whereby said ,change of speed of said disk acts upon said plate to operate the main clutch, substantially as described.

2. In combination in a clutch operating device, a laterally movable plate controlling the operation of the clutch, a disk adjacent to said plate and adapted to be rotated thereby, a clutc'h for changing the'speed of said disk in relation to said plate, and inclined planes on the adjacent faces of said plate and said disk.

3. In combination in a clutch operating device, a laterally movable plate controlling the operation of the clutch, a disk adjacent to said plate and adapted to "be rotated thereby, a clutch for changing the speed of said disk in relation to said plate, inclined planes on the adjacent faces of said plate and said disk, and a peripheral groove with balls therein in one of said adjacent faces, substantially as described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
